The first driving member 23 is fixed to one side of the support plate 212 of the bracket 21, and one end of the first driving member 23 is connected to one side of a gate plate 34; and the oscillator 24 is fixed to the other side of the support plate 212 to vibrate the support plate 212.

[0041] The powder tube 31 of the mold set 3 passes through the plate surface of the support plate 212 from top to bottom to be positioned in the quadrilateral positioning groove 214; the bottom plate 311 of the powder tube 31 has a plurality of first holes 312 arranged in an array and respectively passing through it up and down; a limit plate 32 is provided below the bottom plate 311, and the limit plate 32 is a flat plate, and the plate surface of the limit plate 32 has a plurality of second holes 321 arranged in an array and respectively passing through it up and down, and the plurality of second holes 321 are correspondingly misaligned and not connected to the plurality of first holes 312.

[0043] like Figure 6 As shown, when the first driving member 23 drives the gate plate 34 to move horizontally forward between the bottom plate 311 and the limit plate 32 to be positioned at a second position B, the plurality of first holes 312 of the bottom plate 311 and the plurality of third holes 341 on the gate plate 34 are interlaced and not connected, while the plurality of third holes 341, the plurality of second holes 321 of the limit plate 32 and the plurality of mold cavities 331 of the lower mold 33 are connected to each other in upper and lower correspondence, and the second vibration of the oscillator 24 allows the metal powder in the plurality of third holes 341 to descend and be filled into the plurality of mold cavities 331 respectively. Figure 7 , Figure 8 As shown, when the first driving member 23 drives the gate plate 34 again to move horizontally backward and be positioned at the first position A, and the guide plate 22 and the support seat 222 descend, the first limiting member 224, the second limiting member 225 and the third limiting member 228 are released, and the lower mold 33 can be taken out to perform subsequent molding processing operations on the uniform amount of metal powder in the multiple mold cavities 331.

[0044] In summary, according to the contents disclosed above, the present invention can indeed achieve the intended purpose and provide a support frame structure that can position a mold set through a support frame structure, and then use a gate plate to move horizontally back and forth between a bottom plate and a limit plate, and use an oscillator to assist in vibration, so that metal powder can be evenly filled into each mold cavity of the mold, thereby ensuring the quality and consistency of subsequent molded products. A support frame structure and a powder filling device using the support frame.
